Abstract: The development and application of mass concrete are a remarkable chapter of modern concrete design and construction history. ACI Committee 207 defines mass concrete as “any volume of concrete with dimensions large enough to require that measures be taken to cope with the generation of heat from hydration of the cement and attendant volume change to minimize cracking.” Early practices of mass concrete construction were primarily the provision of temperature and shrinkage reinforcement, or construction joints. In the last decades, technological advances in concrete design and cracking control have opened up a variety of new applications of mass concrete that significantly reduced the temperature or shrinkage reinforcement with improved constructability and construction efficiency meanwhile enhanced the durability of concrete structures. The experience gained from these projects has laid the foundation for better industry practices and portended further advancements. To give a perspective of the advances, this presentation describes a systematic approach of mass concrete design and respective underground construction applications in which innovative uses of mass concrete have brought significant benefits in cost saving and cracking reduction.
